IMPROVEMENT I N BELT-SHIPPERS.

Specification forming part of Letters Patent No. 36,707, dated October 21, 1802.

To a/ZZ whom it may concern.-

Beit known that I, JOHN C. GOAR, of Jamaica Plain, in the county of Norfolk and State of Massachusetts, haveinventedanew and useful Improvement in Belt-Shippers; `and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, formresenting a front View of a belt-shipper with my improvement.

This invention consists in acertain novel arrangement of an oscillating double elbow-piece and a single spring lockingpawl, in combination with a two-notched shipping-slide, which carries the belt-guide, and with a lever or its equivalent, whereby, when the slide has been locked by the pawl with the guide in either of its two positions for guiding the belt the pressureapplied to the lever or its equivalent to shift the slide for shipping the belt will first cause the elbow lever to disengage the pawl from one notch of and so unlock the slide, and then give the latter the proper movement, and that when, after the movement of the slide has been given,ithe pawl is allowed to enter the other notch of and so lock the slide until the pressure on the lever is reversed.

To enable others skilled in the art to make and apply my invention, I will proceed to describe its construction and operation.

A represents a board or plate or any fixed support which carries all the parts ofthe shipper.

B B are guides attached to the support Afor the reception of the horizontally-moving slide C, to which are rigidly attached the two horns a c', which constitute the belt-guide. At the middle of the lengthof the guide, and near the lower end thereof, the oscillating double elbowpiece D is attached to it by the pin VZ1, upon which the said piece oscillates. In the lower edge of the slide, near the ends of the two lower arms, d d', of the double elbow-piece, are two square notches, c c', for the reception of the square-pointed tooth c of the locking-pawl E, which is attached by a pivot, f, to a plate, F, screwed to the support A, and which is constantly pressed upward by a spring, g,attached to the said plate belowit, and on opposite sides of the upper arm, cl2, of the double elbow-piece there areattached to the slide two stops, h h',

to limit the oscillating movement of the said piece. The pawl E is thick enough for the tooth c to project from the notches c c' under the bottom of the double elbow-piece D. The guides B B are arranged to serve as stops to the horns a a, for the purpose of limiting the horizontal movement of the slide, so that such movement may only be sufficient to ship the belt.

G is the lever operated by hand to shift the slide, pivoted by a fulcrum-pin, j, to the support A, and connected bya rod, H,with a stud, d, secured in the upper arm, d2, of the double elbow-piece D.' y

The operation of the shipper is as follows: The drawing represents the'slide and attached belt-guide c a as having been shifted to the right and the slide as locked by the tooth e of the pawl entering the notch c. To shift it to the left, the lever is to be moved in that direction. The first part of this movement of the lever is ycaused by the action of the rod H on the upper arm, d, of theoscillating double elbow-piece D,to produce the depression ofthe arm d of the said piece upon the tooth e of the pawl E, and so to disengage the said pawl from the slide C and lunlock the latter, and by the upper arm, d2, of the said piece E coming in Contact with the stop h the continued movement of the lever is caused to move the slide to the left until the horn a comes in contact with the guide B and prevents the further movement of the slide, when the notch c', having arrived over the tooth c of the pawl, the spring g, by its upward pressure on the pawl,

causes its tooth e to enter the said notch and lock the slide. To return the slide and its attached belt-guide to the position shown inthe drawing, the lever is moved to the left, andin such movement it carries the upper arm, cl2, of the piece D with it as far as the stop h, and so causes the arm d of the said piece to depress 'the pawl E, and so unlock the slide and bring Instead of the lever G and rod H, there may Vhat l elainms myinventiou, and desire to be used as their equivalent two cords attached secure by Letters Patent, isto the arm d2 of the elbow-piece D, and pass- The combination, with the belt-slide C and ing over pulleys arranged in the guides B B the spring loeking-pnwl E, of the double-act and hanging down to convenient positions, as ing detaeher and slide-mover D, in the manshown in red outline inthe drawing.V Bypull- Aner herein shown and described. g ing the right-hand cord the same effeetis pro- JOHN C.
